A Novel Self‐assembled Nickel(II)‐Cerium(III) Heterotetranuclear Dimer Constructed from N2O2‐type Bisoxime and Terephthalic Acid: Synthesis, Structure, and Photophysical Properties

Abstract

Abstract By self‐assembly of a Salamo‐type ligand H2L [H2L = 1,2‐bis(3‐methoxysalicylideneaminooxy)ethane] with Ni(OAc)2·4H2O, Ce(NO3)3·6H2O, and H2bdc (H2bdc = terephthalic acid), a novel NiII‐CeIII heterometallic complex, [{Ni(L)Ce(NO3)2(CH3OH)(DMF)}2(bdc)], was obtained. Two crystallographically equivalent [Ni(L)Ce(NO3)2(CH3OH)(DMF)] moieties lie in the inversion center, and are linked by one bdc2– ligand leading to a heterotetranuclear dimer, in which the carboxylato group bridges the NiII and CeIII atoms. Moreover, the photophysical properties of the NiII‐CeIII complex were studied.
